A power control system with a power management apparatus and a power monitoring control apparatus for each control segment. The power monitoring control apparatus is provided with: a contribution degree setting unit setting the degree of contribution of each control segment; a device control unit controlling the power consumption of each power using device connected; a priority control unit setting a priority for reducing the power of the power using device; and a device monitoring unit obtaining the priority of each power using device and transmitting the obtained priority to the power management apparatus. The power management apparatus is provided with an optimum control calculation unit determining a control command for controlling each power using device connected. The control command is determined based on: a target value of the total power consumption of all the control segments; the degree of contribution; and the priority of each power using device.

A data transfer device calculates a compression performance value which represents a quantity of data that can be compressed per unit time and a transfer performance value which represents a quantity of data that can be transferred per unit time, and calculates, based on these values, a compression ratio which represents a ratio of data to be compressed and then transferred to total data to be transferred. The data transfer device extracts, from a storage unit which stores data, the data to be transferred, and then compresses part of the extracted data based on the compression ratio, and transfers the compressed data and remaining data to another device. The compression and transfer processes are performed in parallel.

A vehicle information acquisition system includes a vehicle and an information management center. The vehicle includes an information acquisition portion that acquires a piece of vehicle information, which is processed by an information processing unit, based on a set collection condition, and transmits the acquired piece of the vehicle information to the information management center. The information management center determines a new collection condition for the piece of the vehicle information, which is processed by the information processing unit, based on a result of an analysis of the transmitted piece of the vehicle information, and transmits the determined collection condition to the vehicle as a collection condition for a piece of vehicle information to be subsequently acquired by the information acquisition portion to re-set the transmitted collection condition in the information acquisition portion.

Vehicle information acquisition system and vehicle information acquisition method

When connecting a mobile information terminal to a communication network via a public access point, a user of the mobile information terminal is undesirably required to input detailed information for connection to the communication network via a poor input interface. In order to solve this problem, the information acquisition function receives network connection setting information from a setting information distribution server which distributes network connection setting information which is information indicative of settings of connections with communication networks. In accordance with the network connection setting information received by the information acquisition function, an NW connection function establishes a connection with a communication network via an access point.

An electronic information authenticating system is provided which is capable of providing enhanced security of specified electronic information and its related information in the terminal without causing high costs. In a board storing region in a ticket managing board in a portable information terminal, related information passed from a ticket issuing server to which an access is permitted by a board AC (Access Control) unit is stored. A UA (User Agent), ticket board managing server, and ticket issuing server are accessible to the board storing region. An electronic ticket to which consideration on security needs to be given is stored in a secure memory retaining enhanced security, however, the electronic ticket to which consideration on security needs not to be given is put into the board storing region being at low costs.
